【高级技巧】Lua链表：裁决之杖押镖任务的节点串联

local function insertAt(list, pos, node)
    table.insert(list, pos, node)   -- 中插搬移后续全部节点
end

local head = {point = "镖局"}
local n2 = {point = "城门"}
head.next = n2
local function insertAfter(prev, node)
    node.next = prev.next           -- 先接后段
    prev.next = node                -- 再接前段，常数级插入
end
insertAfter(head, {point = "裁决之杖驿站"})
local cur = head
while cur do
    sendmsg(actor, 1, "押镖节点：" .. cur.point)
    cur = cur.next
end
